Normally crushed on desert type stuff. It is an art to crack the little beggers. I read recently about a guy that freezes them prior to cracking, haven’t tried it yet but I intend to. Otherwise it is an activity for the dead of winter while sitting around the cookstove in the out building (also known as the prepper palace).
I’ll try anything. They taste wonderful, but I don’t have the patience to deal with them, nor the strength - even tried a vise clamp.
